rewrite componentDidUpdate(prevProps) into a hook

Question

I would like to rewrite this life cycle metod into a hook:

componentDidUpdate(prevProps) {
  if (this.props.lng !== prevProps.lng && this.props.lat !== prevProps.lat) {
    this.map.setView(new L.LatLng(this.props.lat, this.props.lng), 6);
  } else if (this.props.mapTheme !== prevProps.mapTheme) {
    this.setMapTheme(this.props.mapTheme);
  }
}

I know to use a useEffect hook but couldn't find a good example.

Answer 1

useEffect(() => {
  map.setView(new L.LatLng(props.lat, props.lng), 6);
}, [props.lng, props.lat]);

useEffect(() => {
  setMapTheme(props.mapTheme);
}, [props.mapTheme]);
